I've seen Dr. Penunuri for everything from routine appointments to more serious procedures and she always makes me feel comfortable and informed. She takes the time to thoroughly answer my questions and I never feel rushed out her door. Dr. Penunuri is an excellent physician who I recommend to all of my friends & family.
